Embodiment 1

[0036] The steps of the present invention are:

[0037] 1) Raw material preparation

[0038] MnZn ferrite particles with a particle size of 0.1 μm are pretreated and mixed with ABS resin into the feeding cylinder;

[0039] 2) modeling

[0040] First use computer modeling software to model, and then "partition" the built 3D model into sections with a thickness of 20μm, that is, slices, so as to guide the printer to print layer by layer;

[0041] 3) Set print parameters

[0042] Set the printing speed to 0.05m / s, the printing resolution to 20μm, and the powder feeding amount to 0.02mm 3 / s;

[0043] 4) 3D printing magnetic field orientation

[0044] Start the printing device for 3D printing. The feeder feeds the material into the print head, and heats the print head to 280°C to melt the incoming ABS resin and mix it with MnZn ferrite particles. The print head prints out the fluid mixture according to the set trajectory and speed. During the printing process, a magnetic f...

Abstract

The invention provides a 3D printing magnetic field orientation preparing method of plastic magnets. The method comprises the steps that firstly, a magnetic component, a polymer and other raw materials are prepared; secondly, a computer three-dimensional schematic diagram of the plastic magnets is established, slicing is carried out, and a scanning path is established; thirdly, corresponding printing parameters are set; fourthly, a printing device is started to carry out 3D printing, meanwhile, magnetic particles and the polymer are injected into a printing head, printing is carried out according to the set track and speed after heating and mixing are conducted, in the printing process, a magnetic field is exerted on the work space, the magnetic particles are oriented in the outer magnetic field direction, the magnetic performance is optimized, printing is conducted line by line to form a face, and the three-dimensional plastic magnets are formed through printing conducted layer by layer. The preparing method has the advantages that feeding, melting, mixing, printing and magnetic field orienting are finished at the same time through 3D printing, and the working efficiency is improved; the 3D printing technology is an additive manufacturing method, and compared with a traditional technology, raw materials are saved, and waste is avoided.

Description

technical field [0001] The invention relates to a method for preparing a 3D printing magnetic field orientation of a plastic magnet, belonging to the field of material preparation. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] The working principle of the so-called 3D printer is basically the same as that of ordinary printers, but the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while 3D printers are equipped with different "printing materials" such as metal, ceramics, plastics, and sand. Real raw materials, after the printer is connected to the computer, the "printed materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer can be turned into a real objec...
